ᐅ How much does a turnkey prefabricated house with a granny flat cost?

Apart from that, prices have moved away from 2000€/m² (2000 €/square meter) at the latest since the raw material shortage in spring. Additionally, a granny flat (also called a secondary suite or accessory dwelling unit) is not necessarily equivalent to regular living space. You also need a bathroom, a kitchen, and possibly a room for the necessary utility connections. The partition walls have to be built differently, etc. These are all costs that are already accounted for or not even necessary in a simple single-family house. I think it’s almost heading toward 400k.

What is the plot like? Flat or on a slope?

Why do you want to choose a prefabricated house?

400,000 euros would not be affordable for us. It generally sounds quite hopeless.

The plot is flat. By the way, we want to build a prefabricated house because we believed / still believe that it is cheaper and overall easier to manage.

Thanks for all the responses.

This would be a classic house with a gable roof ("1 1/2 stories"). The entrance area, separated by a staircase, would divide the two apartments, which is more or less easy to achieve depending on the floor plan used. About 80 m2 (860 sq ft) on the ground floor, level for the seniors, and the upper floor (ideally with a small balcony) with 50 m2 (540 sq ft) for the junior. This is a slightly modified standard single-family house from a catalog! Modified mainly because of the entrance area and the second kitchen on the upper floor.

In addition, a small side extension for the building services, possibly with the balcony on top. The technical room that is usually located on the ground floor within the main building would be added to the guest bathroom to create a full bathroom. It should be made fully accessible! The bedroom on the ground floor will have to be sized by taking some space from the living room plus a frequently existing small office.

Additional question: There seem to be countless websites on this topic. How can you find (reliable) providers that offer prefab homes meeting the criteria mentioned above? Is there perhaps a list with a filter or something similar that only shows prefab homes with granny flats?

Maybe start by browsing the forum for about half an hour, then find the appropriate subforum, such as “Construction Costs,” and read the first five posts. After that, you’ll be able to absorb the answers easily. It’s the same with prefab homes. Take your time and read through the existing information—your questions might already be answered.

PS: Take a look at the POINT 131 from Danwood regarding this. Note, the prices do not include the foundation slab, architect fees, transportation, or surveying—initially, you should budget around 50,000 (50k) for these. Plus 50,000 (50k) for additional construction-related costs. This is until you have more reliable figures.
